Wine-bug: https://bugs.winehq.org/show_bug.cgi?id=44893 Wine-bug: https://bugs.winehq.org/show_bug.cgi?id=48641 Signed-off-by: Myah Caron qsniyg@protonmail.com --- Since I don't know how to write a test for this with the wine build system, I've written one here: https://github.com/qsniyg/wine_dll_load_test/tree/b2b64bc8d7d1589cbfeb1dbb53...
The reason for the two DLLs in the test is because I initially believed the issue was caused by the conflict between both binkw64.dll and skse64_1_5_97.dll having a preferred imagebase of 0x180000000 (as noted by Focht).
If --dynamicbase is added to the linker options, it will allocate the DLL top-down rather than bottom-up. This patch fixes the SKSE issue, as it requires its base address to be > 0x78000000.
